ZMOUNTING FOB, IVIAKE-UP FRAMES FOR PRINTING PEESSES.

Application filed September 26, 1921. Serial No. 503,316.

To'aZZ whom it may concern.

Be it known that I, HARRYB. McBnn, a citizen of the United States,residing at St. Louis, Missouri, have invented a new and usefulImprovement in Mountings for Make- Up Frames for Printing Presses, ofwhich the following is a specification.

My invention relates to the printing art and has for its purpose toproduce efficient and set forth in the claims.

and satisfactory means for forcing a makeup frame against any articledesigned to receive an impression, regardless of whether, or not, thearticle is lying in true and exact horizontal plane, or whether or notthe article is of uniform thickness A- further object is to soconstructthe coacting parts that the make-up frame will first contact one side ofthe article to be impressed, and will then have a relatively rotarymotion in seating itself firmly against the article.

A yet further object is to construct the frame so that it may be turnedupwardly, with a rotary motion on its bearings, and be held in position,face up, while the type is being placed therein. y

In the drawings I have illustrated the various parts of my device,reference to which is made in the appended specification ceive themake-up, the dotted lines indicating the normalposition of the frame.

Referring to the accompanying drawings, the reference numeral 10 is usedto indicate the carrying shaft of'the make-up frame, and the numeral 11indicates the make-up frame depending therefrom and rotatably andslidahly, mounted thereon.

The numeral 12 indicates a bearing secured to the shaft 10 and providedwith arms 13 and 14, extending inwardly therefrom to a position over themake-up frame 11, one on each side of the shaft 10, said arms beingdesigned to receive, for rotation and adjustment therein, thescrew-tln'eadcd adjustment shafts 15 and 16, which depend downwardlytherefrom to positions over their respective sides of the make-up frame11. The make-up frame 11 is, as stated, designed for slidable movementon the shaft 10, andthe screw-threaded shafts 15 and 16 are positionedso as not to interfere with this slidable movement, which is designed tobe such as to move the frame 11 until it is out of the plane of theshafts 15 and 16, at which time the make-up frame may be rotated atwill, on the shaft 10. On the shaft 10 I have provided a lug 17,whichlimits the movement of the make-up frame, and a companion lug 18 onthe side of the makeup frame is designed to engage the lug 17,

the construction and positioning of these lugs being such that when themake-up lugs 17 and 18 engage, the make-up frame will be rotatedslightly more than one-half of a revolution, the face of the make-upframe being turned upwardly to receive the make-up, and as the rotationhas been slightly more than one-half, the lugs 17 and 18 will operate,with. the weight of the make-up frame, to hold it in this position.

In ractical operation the shaft 10 is designe to move downwardly orupwardly, as selected by the operator. In desiring to change themake-up, the shaft 10 is moved upwardly, the makeup frame 11 moved by asliding movement, on the shaft 10 until it is beyond the screw-threadedshafts 15 and 16, and rotated until the lug 18 engages the lug 17. Theoperator then inserts the make-up in the make-up frame. The frame isthen rotated downwardly and. moved on the shaft until it is in properposition, underlying the ends of the screw-threaded shafts 15 and 16.These shafts are then adjusted as desired by the operator, to cause themake-up frame to assume any angle desired for meeting the face of thework. By this construction the surface of the work does not necessarilyhave to be in a perfectly true horizontal plane, but may even be onquite an angle and the pressure will be applied to the makeup frameequally, nevertheless.

A very important feature of my invention is the fact that the rotarymounting of the make-up frame ,on the shaft 10 will cause pressure onthe shaft 10 to equalize itself on the make-up frame pressing againstthe work. This is obvious because of the fact that if one edge of themakeup frame contacts the work first, the continued downward pressure ofthe shaft 10 forces the 'make-up frame to equalize itself on the work bya slight rotationon"the shaft 10, thus completely equalizing thepressure that is continued to be applied. In practice this has proven tobe of great service because it has practically eliminatedthe occasionalmackle which so often occurs in printing. Furthermore, my 'rotatalolymounted makeup frame provides for satisfactorilymale ing impressions onwork which may be resting at more or less of an angle from the truehorizontal, or when the article is not of uniform thickness. In additionto these features, it also functions to produce a very satisfactoryimprint upon work which may have more or less resiliency, such as thehack of a book which has been opened and placed in spread position onthe bed plate.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, is:

1. In a printing press, a makeup frame mounted for limited rotarymovement on a carrying shaft; means on the carrying shaft for limitingthe rotation of the make-up frame, said means being such as to alsofunction for retaining the make-up frame in its rotated position,substantially as as shown and described. j

2. In a printing press, a makeup frame rotatably mounted on a carryingshaft; a

bearing secured to said shaft, and screw threaded adjustment shaftsrotatably mounted in screw threaded orifices therein, one

therein, one on each side of the carrying shaft; a lug on the carryingshaft to limit the slidabl'e movement of the make-up frame,substantially as shown and described.

4. In a printing press, a make-upframe rotatably, and slidably, mountedon a carrya ing shaft; a bearing secured to s'aid'shaft, and screwthreaded adjustment shafts rotatablymounted in screw threadedorificestherein, one on each side of the carrying shaft; a lug on the carryingshaft'to limit the slidable, movement ofthe make-up frame; a lug on themake-up frame to engage the lug on the shaft when the makeup frame hasbeen rotated upwardly on the said shaft, the positioning of'the lugs onthe make-up frame and the shaft being such that when they engage eachother the makeup frame will be held in position with its face upward toreceive the make-up, substantially as shown and described.
